fart

: One phrase that a lot of folks use but almost always misquote is "I couldn't care less".
: Most everyone deletes the shortened "NOT" from it saying "I could care less".
: Also, does anyone know where a "fart in a skillet" came from??
: It denotes someone who is too active and hard to catch.

The fart probably emerged from a rectum, they ususally do.
I don't know where you got the skillet from - probably a cookshop.
